There are varying degrees of discomfort during an esophageal ultrasound endoscopy, but the discomfort is the same as when the patient has a general electrogastroscopy, so there is no need to be overly nervous. When undergoing an esophageal ultrasound endoscopy, the patient can relax and cooperate with the doctor to make the examination go more smoothly. Esophageal ultrasound endoscopy is not allowed to be done painlessly because it requires water injection during the ultrasound, so there is a risk of accidental aspiration. If a lesion is found after the endoscopy, the patient will need to consult with a specialist for microscopic treatment or other special treatment, if necessary, under the guidance of the doctor.
